Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down.
With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.
Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.)
Contraction of front and side parts—as cells die off—was observed I some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age—using the head.
The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant.
Matsuzawa’s findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain,” he says, “Think hard and engage in conversation. Don’t rely on pocket calculators.”
第26题：The team of doctors wanted to find out ________.
A) why certain people age sooner than others
B) how to make people live longer
C) the size of certain people’s brains
D) which people are most intelligent
While searching for the origin of personal computer, Shapiro uncovered several computing claims. Stewart Brand, founder of Whole Earth Catalog, says on his Web site that he first referred to a “personal computer” in a 1976 book; and GUI pioneer Alan Kay is said to have used the term in a paper published in 1972.
But a search on JSTOR’s general science archive turned up what Shapiro says is the earliest recorded use of personal computer, in the October 4,1968, issue of Science. The issue contains a Hewlett-Packard advertisement for its new HP 9100A. “The new Hewlett-Packard 9100A personal computer,” the ad says, is “ready, willing and able …to relieve you of waiting to get on the big computer.” The $4900 device---a desktop scientific calculator equipped with magnetic cars---does not seem like much of a computer nowadays. And at 40 pounds, it was not very personal, either. But according to Shapiro, it was the first device to be called a personal computer.
1.The term “personal computer” first appeared().
A.in Byte magazine
B.in a Hewlett-Packard ad in Science
C.in a 1974 book
D.in a paper published by Alan Kay
2.What is JSTOR ？()
A.It is an online database
B.It is an academic journal
C.It is a kind of computer software
D.It is a research organization
3.Shapiro succeeded in his research for the origin of the term personal computer by().
A.looking into the Oxford Dictionary
B.digging into magazines that are more than 150 years old
C.scanning JSTOR’s general science archive on line
D.focusing on academic journal such as Science
4.With a HP9100A, according to the Hewlett-Packard ad, you().
A.can easily get on the big computer
B.do not have to get on the big computer
C.can save a lot of money
D.will be willing and ready to do scientific work
5.What do we learn from the passage about the first device that was called personal computer？()
A.It looked very different from the PC today.
B.It was small, light and easy to carry around.
C.It was as efficient as a big computer.
D.It relieved people of a great deal of tedious work.
So why do manufacturers keep on designing and producing VCRS that are awkward to use if the problems are so obvious？
First, the problems we notice are not obvious to technically minded designers with years of experience and trained to understand how appliances work. Secondly, designers tend to add one or two features at a time to each model, whereas you or I face all a machine’s features at once. Thirdly, although find problems in a finished product is easily, it is too late by then to do anything about the design. Finally, if manufacturers can get away with selling products that are difficult to use it, it is not worth the effort of any one of them to make improvements.
Some manufacturers say they concentrate on providing a wide range of features rather than on making the machines easy to use. But that gives rise to the question, “why can’t you have features that are easy to use？” The answer is you can.
Good design practice is a mixture of specific procedures and general principles. For a start, designers should build an original model of the machine and try it out on typical members of the public-not on colleagues in the development laboratory. Simple pubic trials would quickly reveal many design mistakes. In an ideal world, there would be some ways of controlling quality such as that the VCR must be redesigned repeatedly until, say, 90 percent of users can work 90 per cent of the features correctly 90 per cent of the time.
第36题：The author had trouble operating his VCR because ________.
A) he had neglected the importance of using the timer
B) the machine had far more technical features than necessary
C) he had set about using it without proper training
D) its operation was far more difficult than the designer intended it to be
"Unsolved History"
If NASA engineers invented a time machine tomorrow, you can be sure historians would be shelling out top dollar for just a few minutes at the wheel. History books are filled with mysteries, hotly debated issues and question able stories, and if you could just get a look at the real scene of the event, you could finally answer a lot of these big questions. Imagine witnessing the beginnings of the American Revolution, the historic battles of the Civil War or any of the major events that have defined the past 100 years.
Discovery Channel's hit weekly series "Unsolved History" has set out to do the next best thing. Using the most advanced investigation tools modem technology has to offer, the "Unsolved History" researchers attempt to reconstruct a famous event by piecing together any hard evidence that remains. Instead of relying on what the history books say alone, the investigators take a fresh look at the available facts.
The basic idea is to approach these historical mysteries in the same way criminal investigators approach modern ones. By looking at each historical event as a crime scene, the show's researchers can scientifically devise the most likely scenario for the historical event in question. So far, their conclusions have been both surprising and enlightening.
What does it take to do all this？ It turns out you need a large staff of historians, scientists and investigators, and a lot of sophisticated equipments. Just as in a real criminal case, investigators bring hard evidence and human intuition together to come up with the most likely explanation of what actual happened.
The result is an interesting, highly unique show. It's part history, part detective story and part technological showcase.
The Premise
"Unsolved History" revolves around interesting stories from history that have an element of mystery about them. The producers' first challenge for every episode is to come up with a suitable subject. They are generally drawn to three types of episode subjects: topics with a certain amount of controversy surrounding them, topics that are misunderstood by the general public, and topics with big lingering questions.
In the first episode, for example, the producers investigate "Pickett's Charge," a fairly controversial event, at least among Civil War buffs. Was Confederate Major General George E. Pickett's infamous attack in the Battle of Gettysburg a desperate, last-gasp failure from the out-manned Confederates, or was it a valiant(英勇的), heroic last stand,as the Southern army claimed？ The "Unsolved History" crew concludes that neither version is accurate. In another controversy-driven episode, the researchers attempt to separate folk mythology from fact in reconstructing what actually happened in the battle of the Alamo.
In a later episode, the research crew gets to the bottom of a widely misunderstood subject, the Boston Massacre. The common view among most Americans is that British soldiers fired upon a crowd of innocent civilian colonists, in an act of inexcusable oppression. The evidence, according to the" Unsolved History" crew, paints a very different picture—they assert that the British soldiers, backed into a corner by an angry mob, fired in self defense.
In another episode, the crew investigates a different kind of "police incident", the famous shoot-out at the O.K. Corral. In the popular old west mythology, four lawmen, led by Wyatt Earl？ And gunslinger Doc Holliday, valiantly protected the town of Tombstone from a gang of villainous outlaws. The Unsolved History crew approaches the event just as they would a police shooting today, using modern forensic(法医的) tools to determine if it was "clean" police work or an abuse of power. Just as with the Boston Massacre, the investigators conclude that this was not a prudent use of police power.
